The Wheel Rim of the three wheeler bike was modelled using solidThinking EVOLVE. We use solidThinking Inspire for Topology optimization and use cyclic symmetry constraints to create a symmetric result. Inspire provides multiple optimization constraints, stress constraints & mass targets are used to achieve optimal designs, which suits given loading conditions. By carrying several runs, we find that cyclic symmetry with 5 sectors, split draw, and default thickness constraint yields a suitable design output. We are able to achieve a mass saving from 4.6 kg to 2.9 kg. We see further scope of topology optimization on the optimized structure using various other Inspire options. We encourage all academic students to try out the best possible combinations of manufacturing constraints & come up with new designs.
